Transmission of digital signals is today more frequently used than transmission of analog signals. One reason for this is that a digital signal is less sensitive to noise than an analog, another reason is that almost all signals today are handled in a digital format. This thesis describes the development of a system that receives digital video signals through FireWire. The standard for FireWire, which is a high performance serial bus, is under development. Today the standard of the bus supports transmission of data with a speed of up to 400 Mbit/s.

A study based on the consumer buying decision process to discover the typical use of the Internet in the consumer buying decision process when buying clothes. The matter is researched through an Internet survey which discovers how the consumer use the Internet in each step of the buying decision process by using predetermined options. As a result, the conclusion is that people most commonly use the traditional alternatives in the buying decision process of clothes. However, information about a product is often collected on the Internet, mostly on different webshops. The main reason, for people to buy clothes on the Internet, is that the consumers consider it is more convenient and time saving.

This project is about investigation and improvement of a V-plow for the company Swekip. A V- plow is used for snow removal but this product has been found to have deficiencies in its construction, breaking down and not living up to the desired objectives. This is because the product is ordered from a company in China where they have some problems with understanding the purpose of the plow.Initially the existing plow is investigated, all the shortcomings set out and examined, what is wrong and what needs improvement?When the solutions were done they were evaluated and examined that they actually live up to the desired requirements.This assignment is a pure construction project where the majority is implemented in CAD, where models are developed and FE analyses are carried out. But the project also includes a feasibility study, idea study and hydraulic design.The results are presented in the form of a CAD model and associated drawings that will serve as the manufacturing basis for the new V-plow.

This study is an attempt to develop the discussion about self-injury with the aid of philosophical discussions about understanding. I will present a reading of the discussion between Michel Foucault and Jacques Derrida about reason and madness, and also an interpretation of the Derrida and Hans-Georg Gadamer encounter. These readings focus on the concept of understanding, on the possibility to understand the other and on the possibility to reach out from reason toward the irrational. The project to formulate an ethical approach to self-injury by Nancy Nyquist Potter is then used to bring the question about understanding to life. I conclude that the project of Potter, formulated as ?uptake?, is weakened by the fact that she fails to recognize the underlying philosophical problems in stating the possibility to understand the meaning of something that until today has been considered meaningless..

The purpose of this study is to exam how two environmental organizations reason about the loss of biodiversity. The research questions are; what is the view in these organizations regarding biodiversity? What are the underlying environmental discourses behind their reasoning, and how do they reason about the risks associated with the loss of biodiversity? As a first part of this thesis a thorough review of existing literature and online resources about the actions of environmental organizations was conducted. Two organizations were interviewed, World Wildlife Fund (WWF) and Naturskyddsforeningen. The questions for the study were analyzed in light of Dryzek´s (1997) reasoning about environmental discourses and using the concept of risk by Beck (1998).

Weathering on rocks is an important component of the world?s geomorphology. One way to measure weathering on rocks is to analyse rock hardness. This is a study conducted in the northern hemisphere on granite rocks in Uppsala, Sweden. A Schmidt hammer is used to create a correlation analysis between the aspects on three glacial erratic boulders and rock weathering.

The aim of this thesis is to investigate the reason behind thedecision to open libraries at subway stations in Stockholm.The theoretical framework for the study is Douglas Raber´s threeideologies, social activism, conservative response and populistinitiative. The study includes interviews with librarians and apolitician responsible for the service and documents with plansfor the Public Libraries development during the period. Theempirical material was examined with an idea- and ideologicalanalysis.The conclusion is that the concept of the subway libraries consistsof a combination of the three ideologies but the most evidentare those of populist initiative and social activism.The reason for opening libraries at subway stations is to makethe libraries more easily accessible, to attract new visitors and tomake the Public Libraries service more visible. These smalllibraries have a function as a market place for the Public Librariesand as a meeting place in the city..

Survey´s purpose is to illustrate why and how the process happened, when the seferades had to move from Spain in the last years of 15th century to the Ottoman Empire and how the authors have discussed this. How the seferades were treated by the Turks and the sultan, how teh Jews taught the people in the empire, to use the new innovations. The different results showed that the ottomans also gave great chances to the Jews and they became a powerful group of the palace in the empire.The results also showed that the authors are divided into two groups, one group defending the sultans act, and the others are not. The main reason for the ottomans to open their doors for the seferades was to take advantage of their konwledge. The reason for the attack by the western authors on the sultan´s decisions, are more complex and needs to be explained.

Adam Smith?s economic theory is often subject to criticism, in which it is claimed to be inherently inconsistent. Recently, criticism from well-known scholars has arisen claiming Smith should be characterized a labor value theorist anticipating Karl Marx. This study seeks to analyze whether such criticism is legitimate. Firstly, the economic theory of Smith is discussed in terms of consistency, and secondly, a number of typical and main points of the critique, from the most influential of his contemporary critics, are lifted up and analyzed.

The reason behind this essay has been to study if previous research is relevant for Jehovah?s Witnesses in Sweden and see if secularization has affected the organization or not. The empirical material is made from two qualitative group- interviews and open observations during two meetings in the Kingdom Hall. These studies were performed in Oskarshamn and Mönsterås during the month of February. The reason that these studies have been limited to Oskarshamn and Mönsterås is mainly because they were the only ones willing to do an interview.  According to previous research by James A.

The subject singing in elementary school changed its name to music in 1955 and with the name change followed a change in the content of the topic. In my study, I examine the perspective of how song as a subjekt has changed in the basic school curriculum texts. As a complement to text analysis, I used interviews in which two music teachers with long service in primary school were interviewed. My survey shows that there has been a clear change of the contents of concept song from being a pure skill where the aim was the vocal line benefits in different contexts and is today a vocal expression that can be embodied in many different ways. Curriculum texts have not been crucial to the changing content of the concept song.

In this paper I have tried to find out the reason the medieval town of Vä was created. I have studied several different areas in witch all, in one way or another, have had an effect on the making of Vä. This areas includes topography, iron production, mill handling, religious effects, royal affliction and also if the name Vä could tell something about Väs history as a religious cult. I have also looked at two other places not far from Vä, the medieval harbour town Åhus and the big village of Fjälkinge. By comparing these three places I tried to find out what Vä had that the other places did not, which made Vä turn in to a town.

The aim of this study is to investigate how preschool teachers reason about gender stereotypical and gender neutral toys and other material. I would also like to see how the pedagogues reason about gender segregation when it comes to toys. To investigate the issue, I have interviewed three pedagogues from different preschools. The results showed that the work procedures differed a bit from school to school, although they all wanted to achieve the same goal. A goal that our curriculum mention as well: Not to make a difference between boys and girls.

In this thesis we study four groups of students in grade 8, 9 and 10 when they try to solve a classical mathematical problem: Which rectangle with given circumference has the largest area? The aim of the study was too see how the students did to solve a mathematichal problem?The survey shows that students have rather poor strategies to solve mathematical problems. The most common mistake is that students don?t put much energy to understand the problem before trying to solve it. They have no strategies.

Lifelong learning (LLL), a concept dating back to the 1920s, is much used both by the OECD, UNESCO and the EU. But while intergovernmental think-tanks and supranational organisations often use the term in a positive sense, many (not least scholars) are critical of the term. The critique either deals with the lack of a universal definition, that the implicit responsibility for LLL has shifted onto the individual, or that the meaning of the term has shifted from a humanistic one linked to the personal development and a better society to a neoliberal one that involves growth, competition, globalisation and human capital theory. This study is based on interviews with nine trade union representatives on their understandings of lifelong learning. The results showed that while LLL was positively viewed by most, there was virtually no communication vis-à-vis members on the topic, most trade unions have no policy regarding LLL, and responses from representatives were sometimes self-conflicting..
